Buckling panel orientation relative to material direction

(1/1)

RobDexter:
Hi,
Is there a way to define buckling panels at an angle to the material orientation, or must they always be aligned?
I have a number of panels across a single skin with a range of orientations.  Some would be better represented by angling them relative to the material system.  Is this possible?
Best regards,
Rob.

Rob,

From an analysis perspective, we recommend to align the material axis to the assumed buckling x-span direction. HyperSizer uses the material direction to compute the panel spans and radius of curvature. Unfortunately there is not a way in HyperSizer to assign an angle between the material axis and the panel assumed x-span direction.

If you update the material axis in HyperSizer, be sure to recompute the buckling spans for that component. This option is available in the component drop-down in the FEM viewer. See link to help system below:

Hope this helps.
